To be more specific, Xemu was created/discovered/pulled out of a bag of Scrabble letters by L. Ron Hubbard, creator of Scientology. Xemu is responsible for creating body thetans and all that stuff. Given what you see here, you might think such an entity would make an amusing anime character, but in fact many many people believe Xemu was a real entity. Who? They are Scientologists. There is a wondrous writeup regarding the tale of Xemu on the Scientology node.

The Church of Scientology has tried to repress this formerly secret character by many means, but unsuccessfully, thanks to alt.religion.scientology, brave former Scientologists, and the Internet in general. If you have any friends considering becoming Scientologists, have them read about Xemu first.
